SUBJECT: Wahl DIGI-STEM Self Powered Digital Read Thermometers Series DST 200 and DST 300
The Wahl DIGI-STEM digital read self powered thermometers series DST 200 and DST 300 have been reviewed and found to comply with the applicable provisions of the Grade A Pasteurized Milk Ordinance (PMO) for use in milk storage tanks and refrigerated rooms. These battery operated thermocouple based thermometers may be used in storage tank and room applications where mercury-in-glass or bi-metal thermometers have traditionally been used.
These thermometers have been found to meet the applicable Appendix H criteria. They may be adjusted if necessary. A low battery results in a flashing but accurate read. Loss of battery will result in a blank read.
Both series have thermowell or 3A sanitary fittings and connections.
